mshta.exe process keeps running after closing HTA

I'm developing a HTA app, which shows pdf files in an iframe by dynamically setting src of the iframe.

HTML:

<iframe id='preview' src='' application='yes'></iframe>


The relevant script:

var path = 'some_path/file_name.pdf';
document.getElementById('preview').src = path;


This works well, but when I close the app, I can still see mshta.exe running in Task Manager's Processes tab. If any pdf is never loaded to iframe, the mshta.exe process is terminated properly. There's also no troubles if a .htm file is loaded instead of a .pdf. The problem occurs only, if any of the loaded pdfs is a 3D pdf, which is run by A3DUtility.exe.

Loading a .htm file to iframe in onbeforeunload handler doesn't fix the problem. The only working solution I've found, is to kill A3DUtility.exe process via WMI (the script below). However, it's a bit brutal way to close a program, since I can't be sure if there's other windows running an embedded A3DUtility.exe too.

beforeTopClose = function () {
var pdf,
pdfs = new Enumerator(lib.wmiService.ExecQuery('Select * from Win32_Process Where name = 'A3DUtility.exe''));
while (!pdfs.atEnd()) {
if (pdfs.item().CommandLine.indexOf('-Embedding') > -1) {
pdf = pdfs.item();
}
pdfs.moveNext();
}
if (pdf) {
pdf.Terminate();
}
return;
}


Is there anything I can do to close a 3D pdf within iframe properly before closing the app?
